fluid through conduits of large diameter -it has been vcustomary to employ also-called spectacle valve, which comprises a plate, one portion of which is solid and the other provided with ana erture. When the gas is to be interrupte in its flow, Athe plate valve is moved into such positionthat the solid portion of the plate intersectsl the cross-pection of the conduit, whereas when the gas is to pass freely through the conduit the plate is` moved so that the apertured portion of the same corresponds to the crosssection of the conduit. Great diiiculties have attended thev use lof this device, both on account of the fact that the valvecannot be made gas-tight and by reason of the fact that the plate is moved from one po`4 sition to another only with the expenditure of great force.

The pipes or conduits between' which my improved plateA valve is used are provided with ianges, and either of .two or `more separate removable membersl which constitute a portion of the valve may be placed between said flanges. The first of these members is continuous, whereas the second is in the form of a ring. When one of these. removable members has been placed in position the flanges of adjacent pipes are brought into contact with said member by means of turn-buckles, or the like. On the other hand, when the member is to befremoved, the turn-buckles are loosened 1 and the ianges are thus slightly separated from the removable member; the .turn- -buckles on lthe upper part of the anges Specification of Letters Patent.

Application led November 6, 1911. Serial No. 658,708.

In this way the leakage of gas is prevented and the whole adjustment'V of the valve mechanism is easily attained. -These and other advantages of my invention will -be more readily understood by reference to the accompanying drawings, in 'which- Figure 1 isa transverse'section through a, conduit, taken'j on the line 1 1 lof Fig. 2;

Fig. 2 is a partial side elevation and partial j justed and the -ianges are tightened against the valve member, as heretofore described.'

longitudinal section of the parts' shown in j' i Fig. 1; and, Fig. 3` is a longitudinal section through one of the removable valve members.

' The adjacent pipes or conduits 5 are p rovided near theirl edges with the flangel members 6, lpreferably held in position by means of lrivets or the like. 'The projecting portion '7 of eachl of-the flange members 6 preferably has aring surfaces on its outer edge. The portion 7 of each ofthe flange members 6 1s interrupted at intervals, as

indicated at|8. Connecting the flange members of adjacent pipes 5 is a' plurality o'f turn-buckles .9, the4 fiange engaging members of which have a shape adapted to engage the portion 7 of. each of the flange:

members 6. A removable valve member 10 1s adapted'to be inserted between Athe ends of adjacent pipes to interrupt the supply of j gas or other fluidv passing through said pipes. The valve member 10 is provided with an apertured boss 11, to4 which the hoist of a crane may be readily attached, and, if desired, `the auxiliary apertured bosses 12 may also be used. In addition toV the continuous valve'member 10 I also provide aremovable .valve member 13, which is in the form of a ring having the aperture 14.' I may also provide additional valve Y ,members havlng apertures of various s1zes,

according to the amount of gas or other fluid which it is desired to allow to pass through the conduit. I

Having thus descrlbed the construction of theparts used in my' invention', the operaj' tion of thes'ame may -now bereadily understood. It will be4 evident that with the parts as shown in Figs. 1 and 2 all communication betweenthe adjacent conduits 5 fis interrupted. When it is desired to ref move the valve member 10, the turn-buckles 9 are loosened and slipped downwardly` on j the flange members 6. A hoist of a crane may then be attached to the lugs 11 ant. 12,

'and' on account of the loosening of the turn-buckles 9 the valve member 10 may be easily lifted out of position. The valve member 13 may now be placedin the'position formerly occupied by the valve member 10, the turn-buckles are moved to their appropriate positions and tightened, whereby the flange members 6 engage the valve member 13, and the gas is free to How through the aperturev 14, while at the same time the possibility of leakage is avoided on account of the tight connection between 'the flange members 6 and the valve member '13. v` Iffor any reason it is desired toremove one ofthe turn-buckles 9, it is moved yopposite to interrupted portions Spfthe flange members, and may theneas'ily Vbe rings, aplate located between the ends of adjacent pipes, anda turnbuckle for drawing said pipes into 'close engagement with said plate, said turn buckle being provided with undercut recesses adapted tov engage said flanges, substantially as described.

2. In a device of the class described, the

combination of two.pipes located in endto-end relation, a flanged annular' ring secured tO an end of each pipe, the flange on said ring .being undercut and said flange being interrupted at intervals in its periphery, a plate held between the adjacent ends of the pipe, and turnbuckles having undercut recesses in the ends thereof, said turnbuckles being adapted to draw the ends of said pipe in close engagement with said late, said turnbuckles being removable rom said flanges only at the point of interruption of said flanges, substantially as described.

y ,3. A plate valve adapted for use between adjacent pipes, comprising a flange member on each of said pipes, said flange member having a V-shaped projection, a removable valve member adapted to be inserted between said pipes, and a plurality of turnbuckles forming connection between said flange members, the V-shaped portions of which are interrupted at intervals in Order to allow the removal of said turn-buckles,

substantially as described.
